Diagonals and triangles
WebHas two pairs of adjacent sides that are equal length. Diagonals are congruent. One pair of opposite angles are congruent. 1 diagonal creates 2 isosceles triangles when it goes from side to side. 1 diagonal creates 2 congruent triangles when it goes from top to bottom. 1 diagonal bisects angles. WebMar 27, 2024 · Since the diagonals bisect each other and we know their lengths, we have the entire perimeter of triangle ΔADO. How to find the area of a triangle if we know its perimeter? We can use Heron's formula. For a triangle with sides a, b, and c, the semi perimeter s is (a+b+c)/2. Heron's formula gives its area as √[s⋅(s-a)⋅(s-b)⋅(s-c)].
